3. All valves and plugs should be tested in their
individual bores to make certain that free move-
ment can be obtained. All valves should fall freely
of their own weight with a slight tapping action on
the body. In checking, be careful to prevent valve
damage in any way.
4. The manual valve is the only valve that may
be serviced separately. If other valves are de-
fective or damaged beyond repair, a new valve
body assembly should be installed.
5. Before reassembly, make certain springs
can be accurately identified for correct assembly,
